Review: Treo 755p
Clock
When the Treo is in standby, only the four appication keys or the end key will turn the screen on. No other key presses will even temporarily turn the Treo on to display the time. Only using the Phone or Home keys are useful when trying to tell the time. The phone dialer dedicates a line to the date and time while the main menu displays the time in the title bar.
Bluetooth
Pairing the 755p to a headset was simple and worked as expected. The Treo also played nicely with computers and other devices as far as file exchange goes. The only odd behavior was that even when set to discoverable, one of our macs refused to recognize it could send files to the Treo until the two were paired. We were able to send contacts, pictures and even mp3s to the Treo. Sending from the Treo was equally easy once we learned that the term "beam" was strictly reserved for transfer using IR. Instead you have to choose send, which then almost always gives you a choice between Bluetooth and email.
Java
The Treo does not natively run Java applications, though there are Java engines available for the Palm OS platform.
Other
The 755p comes with the full complement of Palm OS applications including a calendar, to-do list, memo pad and other utilities. It also comes with a version of Google Maps and Sprint's On-Demand. The world clock displays the time in two additional time zones but only supports one alarm.
There is a large library of Palm OS applications from third party developers to supplement what is included on the phone.
